Hey Medman, it says in the link above that med graduates had employment rates of about 96%. I'm not a med student, and I'm sure many of those had to go rural i.e. relocate, but that still sounds miles better than most other careers.
Anyway, I think you're going through a bit of a 'grass is greener' phase. Believe me, people like myself would kill to get into medicine and I admit I'm extremely jealous of the people that get in and make it look like it was no big deal. As previous users have mentioned, the desire to go into medicine can't really be pinpointed, but it's a really nice combination of things. At the most basic level, you've got the money and prestige. I don't really see the desire to make money as something bad; after all even making around 150K doesn't mean you're filthy rich nor will it get you a house overlooking the beach in Bondi. 150k will help my refugee parents pay off their mortgage that they're definitely going to have until the day they die. It'll provide a good quality of life to my future kids and ensure I essentially never have to worry about financial struggles ever again.
Medman you brought up the point that there's other ways to go about making such money, but I think you're comparing a majority to a minority. The career pathway for doctors is clear and defined and thus extremely secure and appealing. Sure you go to uni for 5-6 years and go through lots of training (hell the pay for interns and registrars isn't even bad) but if you've completed your degree, you can feel pretty comfortable knowing that you're going to be making 150+K sometime in you life, hell maybe even 200-300K if you specialize in the right thing.
What's the alternative? Do a commerce degree and gun for investment banking? That's even more competitive to get into than medicine. And if you do get in, be prepared to step on a lot of toes, kiss a lot of ass and generally be consumed by your work. Plus you have the drudgery of a soulless office job (sorry not trying to stereotype, but bankers typically aren't happy people) as compared to the satisfying hard work you do in a hospital as a doctor.Those 'alternative' means of breaking 100k that you mentioned only apply to the best of the best in a certain field (e.g. my cousin was the dux of his elec. engineering course when he graduated and is now earning 6figs) and not the majority.
I'll give you an example. I'm still in yr 12, but when I graduate I'm probably going to go into Actuarial Studies. The course is just below medicine in terms of how long you have to be studying to actually become a qualified actuary (there's a long series of exams you have to sit with an external institute). For those that even make it through the course, the job opportunities are far and few between (at least for grads). After all that hard work and exam taking, what's at the end of the tunnel? A round 100K and a future of spread-sheeting in Excel in a cubicle for the remainder of your life. Hell, I don't even like business that much, but what career can I apply my love for science and problem solving to while still earning a good wage and having good employment prospects? Oh right... medicine. If you're aiming for 6figs my friend, you're gonna be working your arse off regardless, the 60-70 hour weeks you have to put in aren't the exception, and at least you know it's going to ease up in the future as you gain more experience.
I've already turned this into a wall of text, but believe me there's other reasons. In what job (besides maybe a paramedic and firefighter) do you literally get to save lives? How better can you leave your impact on society than by alleviating people's pains and seeing them through difficult times? Yes it's hard work, but nobody worth much got through life by cruising. There's a reason why physicians and surgeons continually make the top of 'best career' articles and lists, and I think you'll come to appreciate your job a lot more in the future. Besides, what are you going to do now? Change careers? Might as well learn to appreciate it so chumps like me that'll never get in can at least have the comfort of knowing they picked the right people.
